Abstract
The invention relates to a method and apparatus that uses an R-tree'"'"'s vector data as a mechanism for query and retrieval of raster data in conjunction with or instead of the vector data. The invention relates to a method of storing, indexing and retrieving raster data comprising: storing raster data, storing vector data, and indexing said raster data and said vector data with same index information.
